[rainblocks development retrospective] 22 - Finishing touches

It may have been about the twelfth time that I fixed the animations "for good"
but having eight blocks that moved instead of nine spots that changed was an important logical distinction. "Fast movement" I believe refers to the ability to quickly slide the blocks, but once again, wow, notes could be better. The sound effects came later than the music, but they helped finalize the feel of the game.
